CMD+R should be fine since Big Sur installedI created a USB bootable drive and did a clean install of Big Sur. It just erased the system volume and not the data/app volume. I did have to update the boot rom. I had some problems with the install and have some file issues. I would now like to do a complete clean install (erase both system and app/data volumes) via Internet Recovery. Since I already have Big Sur installed can I just use CMD + R? Will it erase both volumes before the install?
If you just got the machine, there really is no reason to do a clean install. MacOS is not fragmented like Windows. I recommend just doing the update to Big Sur.I've just got a 2020 iMac 27inch which is my first Mac and apple device. Its come with Catalina, I don't see much point in trying to get used to that with Big Sur out. I may as well go straight to that, I know with windows I always liked to do a clean install, but with Macs I've no idea were to start. What is the easiest way for me to just do a clean install, I don't need to save anything, and do I type commands into a terminal or do I boot into a different mode, I'm very much on a steep learning curve
